OSTC 2TR Tech 3.05

When 3.04b is out I decided to see if the Transmitter was working (It's not worked at all for months - well TBH it's never worked under water)

No luck, but I found the battery was dead so I replaced it.

It then 'worked' for about a week (without diving). The little red LED was ...

OSTC 2TR (Tech 3.05)

The compass always has an approx +20 (ish) degree error which is enough to be a navigational problem.

I'm comparing it with a conventional compass not positioned too closely.

I've recalibrated several times with the same repeatable result.

This issue started with the version ...

Hi Ralph
Thanks that worked. I was worried it was broken.

Perhaps if the cal values are void, the firmware should put "COMPASS CAL REQ" in place of "0.00N"

Dedier,

I find it ironic that two months after you posted the previous message OSTC had a serious HSE issue at the Boot Show when a battery exploded. I am told people were hurt.

I'm a hardware and software engineer with 25 years experience in product design and a background in safety systems. A ...

hi,

OSTC2TR Tech.
Just upgraded from 2.98 to 3.01. Compass now only points North.

Image attached.

North
Still North

Suggestions?

In which case, if the fuel gauge is out of calibration (or in a recalibration mode), the battery percent should show 0%/???/CAL or some other value than 99% which is misleading to say the least.

Thanks for the list of puck LED states.

There is another puck state to add to the list;

Red flashing ...

Instead of detecting the battery, detect the hardware.

Is there not a means for the software to probe and ask the hardware what it is?

When I've worked on many products where there are multiple variants I normally have input pins or a OTP PROM that tells the software what the hardware is, defined ...

The puck first goes green, but then flashes green after 10 seconds or so.

The display shows 99% charge (in yellow), T4: 3.7V
Which is wrong, no way is this 99%. A fully charged LiIon is 4.2V until the charger is removed, anything less damages the battery.

Last time this happened I just waited but ...

Does this mean HW have finally fixed the issue.

I've been waiting for my transmitter for almost a year.

Let us know how you get on when you dive it.

Suggestion:
Devices with the internal battery should detect the hardware and not offer a battery selection in software after a restart whhen the battery is fully discharged or via the reset menu.

The battery selection should be fixed.

Inadvertently selecting the wrong battery means the charge ...

My OSTC 2 TR seems to have a charging bug.

1: It does not always like some USB sockets, even ones rates at 2.1A. After a while the puck glows red and it stops charging.

2: If the device is left to completely discharge, on next start it says new battery - fine. I select internal 16550 and it ...
